私はSpringとHibernateを統合しようとしています。この機能を使用してデータをデータベースに保存したいと思います。私のファイルは次のように添付されています。Spring-Hibernate統合フレームワーク
Employee.java
package springhibernate;
public class Employee {
private int id;
private String name;
private float salary;
public Employee() {
super();
}
public Employee(int id, String name, float salary) {
super();
this.id = id;
this.name = name;
this.salary = salary;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public float getSalary() {
return salary;
}
public void setSalary(float salary) {
this.salary = salary;
}
}

@SuppressWarnings("deprecation")
public class InsertTest {
public static void main(String[] args) {

Resource r = new ClassPathResource("applicationContext.xml");
BeanFactory factory = new XmlBeanFactory(r);
EmployeeDao dao = (EmployeeDao)factory.getBean("d");
Employee e = new Employee();
e.setId(114);
e.setName("varun");
e.setSalary(5000);
dao.saveEmployee(e);
}
}
次のように私は例外を取得しています上記のコードを実行中。私は必要なものがあればすべてのjarファイルをインクルード/追加しました。私はまた、stackoverflowに関するいくつかの関連する質問を見たが、適切なヒントを得ていない。

は、誰もがこのエラー/例外から抜け出すに私を助けることができます。
ありがとうございます。
'org.hibernate.JDBCException'クラスを使用すると、使用しているかに応じてバージョンに' hibernate.jar'または '休止状態-core.jar'に存在すべきであり、 。あなたの質問を更新し、あなたの依存関係をバージョンと共に投稿してください。また、それらの依存関係がターゲットビルド（おそらく戦争）に含まれていることを確認してください。また、競合に依存しないことを確認してください。同じバージョンのjarファイル – pleft
